T o all 'whomit may-concern:

Be it known-that I, PINKNEY G. LEWIS, a citizen ofthe United States, residing at Milwaukee, county of Milwaukee, and Statev of Wisconsin, have invented new and'useful Im rovements in Sheet-Music Turners, of

which the following is a specification.

T he object of my invention is to provide a devlce by which the several sheets of a musical composition maybe successively turned' by ressure a plied to a pedal by the foot of a p ayer Whi e renderingsuch composition upon a musical instrument, whereby the `annoyance heretofore experienced in manually'turning the sheets while renderin la piece of music, is avoided. The liability o turning more than one leafat a time or of the .music dropping and becoming disarranged during the performance is entirely overcome.v

T e construction-of my 1nvent1on 1s eX plained by lreference to 'the accompanying drawings in which, f

AFigure 1 is a, perspective light piano.- Fig. 2 is a front view, part 1n Section. Fig. 3 is a detail in vertical section, showing the mechanismfor communicatin motion Ifrom one of the two dal-actuate shafts to the vertical shaft. ig. 4 is a bottom view of the supportingjrame, showing a portion of the interior and exterior pedal actuatedshafts and a part ofthe mechanism for 'communicatin motion. from the res ective pedal actuate .shafts to the vertica shaft.

1 5 is a transversevertical sectiondrawn .gi on line :iz-:t of Fig. 4. Fig. 6 represents one Vof the pedals removed'from the pedal actuated shaft. Fig. 7 is a side view, and Fig. 8 .is-a top view of the mechanism for hol in and turning the several sheets of a musica composition'. Fig. 9 is a side view of the seg-- mental gear for operating the sheet su por-t- Vboing removed with the rod 13. Fig. 11 is asimilar view ofthe.

ing arms. Fig. l1() is a detail plan view of the mechanism for communicating motion from the horizontal pedal actuated shafts to the vertical shaft in their normal position, when at rest, and the late 46 and casing 44 the tubular ortion of same in their operativerelation to each other as' they appear when the pedals. are being operated, j

y.Like arts are identified by the same reference Igures throughout 'the Several views.

The sup orting base 1 of my device rests upon the oorin close proximity to the inof Amy device as lit 1s used 1n `connection with an ordinary upfurther.

strument 2 in front of which a musical com. position 3 is centrally suspended by the leaf actuating arms 4 andclamps 5.' Pedals 6 and 7 are employed to'actuate the arms and turn the sheets.

Assuming that the several -arms are connectedwith the several sheets of a piece of music and that they are all turned toward the right preparatory to 'rendering the music, Inotionis communicated from the pedal 7 to the first and successively to each arm 4 of the series, as follows: from the pedal 7 to the exterior pedal actuated shaft 24 through the pedal supporting arm` 8 and from thence to the .shaft sup orted radial arm 25, sprin actuated pawl) 26, star wheel 12, vertice.

.shaft 13, (a top en'd 'view of which is shown in Figs. 10 and 1.1, the cap 46 being removed) miter gear 14, (located at the upper endof said shaft,) miter gear 15 (meshing with said gear 14),gearsupporting shaft 16, miter. gear 17, miter gear 18, gear supporting shaft 19, segmental gear 20, se mental `gear 21 and from thence to one ci said arms 4 of the series, the respective arms 4 of the series beying each provided with a spring actuated clamping ,mechanism 5, which are adapted to engage the respective sheets of music which it is desirous to turn.

v The `paWl 26 is provided with an actuating spring 27 by which it is retained in position to contact with the arms 12 and 12 of said star wheel12 and said wheel 12 is provided With six radial arms, or at least one for each of the leaf actuating arms 4 and the stroke of the pawl supporting arm 25 is such as to re-- volve said star wheel one step, or in the construction illustrated, one-sixth of a revolu tion with each stroke of the pedal and no l The star wheel and the pawls 26 and 11 constitute a reversible ratchet feed mechanism. Thus it'- will be understood that with each downward stroke upon the pedal 7, the star Wheel 12 will'be revolved onesiXth of a revolution, whereby the segbrought in contact with the stationary s'top 1c 22, (see Fig. 3) thus reventing the star wheel from being turne further. When the arms have been thusturned from right to left, they are returned to their former position in their reverse order, by successively ressing downwardly upron the pedal 6. lotion is communicated om the pedal 6 to the star wheel 12 through the arm 8, interior shaft 7 pawl supporting arml 10 and pawl 11, which pawl 1 1 is pivotally connected with the arm 10 by the screw 27 andis yieldingly retained in position to contact with the ra'dial arms 12 of the star Wheel by the splung 1 1. The pawl 11 is located upon the Opposite side of the star wheel from the pawl 26, and saidpawl, as it moves forward, will contact with said wheel upon the opposite side of its su porting shaft, whereby said star wheel will be revolved in the opposite'v direction from that which is communicated to it when actuatedby'the awl 26.v y

The segmenta gear member 2O comprises live circular disks A, B, C, D and E,'all of which are rigidly connected togethervby a plurality'of pins 28, whereby they are allk adapted to revolve togetherand each of the disks A to E inclusive are provided with a 'segmental set of teeth 29 located in successive segments ofthe member20, whereby the sets`of teeth 29 on the successive disks, are located along a spiral line extending around the member 2,0 and come intoaction l successively, as the member 20`is rotated.

Each arm of the series is provided witha gear segment 21 adapted to mesh with the teeth 29 of the corresponding disk. When in either extreme position one ofthe sides 30 or 31 of the segment is brought in contact with the periphery of the corresponding disk, whereby the further movement of the arm 4 is arrested and said arm will remain at rest and theteeth of the disk are free to pass said gear segment, while the gear segment formed in the next member of the series -Will be brought in position to act upon the gear '55 segment of the next succeeding arm of the serles.

While I have shown the `segmental gear 20 formed of a plurality of-disks connected together by rods 28, itis obvious thatif desired such parts A to E inclusive may be formedintegrally from a single piece of metal, but for convenience of construction in cuttin the gear segments thereon, theyare pref era l. formed separatel and'thereafter secure together, when t e miter gear 18 is rigidly secured to the upper disk of the series in osjitionv to be acted upon by the gear 17.

' Vhile the respective shafts 7 and 24 are adapted as stated to`be revolved a partial revolution in one direction by the downward pressure upon said pedals they are respectively adapted to be revolved in the opposite direction by the action of the springs 32 and 33. Said springs 32 and 33 are rigidly connected at one end to one 'of the arms 34 .of 75 the su porting base while their opposite ends are a apted to contact with the respective Y lugs 35 and 36 of the radial arm 10 and 25 upon the opposite sides of said arm support-\ ing shafts, whereby as'the respective pedals .50 are depressed the actuating springs are thrown back by contact with said lu s and assoon as said edals are released', `wil react and restore sait pedals to their normal posiu tion. g5

The clamps 5 each comprise 'a stationary bracket 3 7 and spring actuated arms 38, 38.

"lhe' arms 3S are pivotally connected with the bracket 37 bythe pin 39 and pin supp'orting lugs 40. Said arms 38 are Yleldin ly re- 90 tained in contact with the brac et 37 4y the spring 41, which spring 41 is support-ed in connection with said parts 'uponthe pin 39.`

The central portionof lsaid spring 41 has contact bearings withthe supporting `arm 4,` while its respective ends are wound around said supporting pin 39, and yieldingly bears against said arms 3S, whereby said arms 38 are retained in contact with tha-opposing bracket 37. v

.42-is a rectangular bar which is-revolubly supported between the bracket 37 and the arms 38. The shape of said bar 42 is such that when the actuating arm 43 is in the vertical positionshown, said arms' are yieldingly 105 retained in contact with the sheets by the resilient action of said spring 41. Vv'hen, however, the arm 4.3 is turned at right angles to the position shown in Fig. 7, said arms 38 are thrown' back and the sheets of music 110 released, The specilic construction of the clamping mechanism is not material.

'l' he horizontal shafts 7 and 24 are rev- `olubly supported beneath the horizontal arm 44 of the supportingvbase 1, while the 115 revoluble shaft 13 is .inclosed and supported' by the stationary tubular casing 44. The casing 44 is connected with the base -1 by the plate 46 and a plurality of screws 47. The rcvoluble shaft 16 is inclo'sed and sup- 120` v ported by the stationary sleeve 48, which `sleeve 48 is rigidly connected with the casing 44. by the angular connection 49. The segmental ear 20 is revolubly supported upon the sha t 19 within the inelosing sleeve 50., 125 The'l sleeve 50 is rigidly supportedfrom the shaft inclosing sleeve 48 and said supporting base and connecting mechanism are made sufficiently rlgld to retam all ot' the operative parts 1n thelr proper relative position. 130
